    • In a method for reducing detrimental phenomena related to disturb voltages in a data storage apparatus employing passive matrix addressing, particularly a memory device or a sensor device, an application of electric potentials conforming to an addressing operation is generally controlled in a time-coordinated manner according to a voltage pulse protocol. In an addressing operation a data storage cell is set to a first polarization state by means of a first active voltage pulse and then, dependent on the voltage pulse protocol, a second voltage pulse which may be a second active voltage pulse of opposite polarity to that of the first voltage pulse, is applied and used for switching the data storage cell to a second polarization state. The addressed cell is thus set to a predetermined polarization state as specified by the addressing operation. The data storage cells of the apparatus are provided in two or more electrically separated segments such that each segment comprises a separate physical address space for the apparatus. In an addressing operation the data are directed to a segment that is selected based on information on prior and/or scheduled applications of active voltage pulses to the segments.

    • In producing discharges in a load element such as a magnetron sputtering device, electric pulses are provided from different electric pulse sources, e.g. three or more electric pulse sources. The pulse sources are controlled by a control and monitoring unit to give the element electric pulses different heights and start and end times. The element electric pulses are summed, such as by connecting the pulse sources in parallel to the load, to form resulting, relatively long electric pulses. Each of the resulting electric pulses can have a portion that has a substantially constant level and then the substantially constant level is formed from at least two element electric pulses having the same pulse height. The resulting electric pulses are applied to electrodes in the load. The element electric pulses can have the same polarity such as being half a period of a sinusoid oscillation of a single frequency. Then the time intervals between starts of successive element electric pulses are relatively short such as not being not larger than one third of the period of the sinusoid. For example, the resulting electric pulses can have a substantially rectangular shape, a shape including two different substantially constant levels or have a substantially triangular shape.
